Structure of Tire

Tread
This thick layer of rubber provides the interface between the tire and the road. Wear-resistant
rubber is used to protect the carcass and belt against fractures and impacts and to deliver a long
driving life.
Shoulder
Located between the tread and sidewall, the shoulder rubber is the thickest so that the design
must allow for the easy diffusion of heat generated within the tire while driving.
Sidewall
The part between the shoulder and bead, the flexible sidewall protects the carcass and enhances
the ride. A tire's type, size, structure, pattern, manufacturing company, product name and various
characters are indicated here.
Bead
The bead attaches the tire to the rim and wraps the end of the cord fabric. Comprised of the
bead wire, core, flipper and other parts, the bead is generally designed to be slightly tight around
the rim so that in the case of a sudden drop in inflation pressure, the tire will not fall off the rim.
Carcass
As the most important framework of a tire, the entire inner layer of cord fabric is called the
carcass. The carcass acts to support air pressure, vertical load and absorb shocks.
